At present, the existing injection molding machine generally adopts the way of hopper cooperating with elevator to send the material into the feeding bin of the injection molding machine. Specifically, the robot grabs the material bag, and then the bottom of the material bag passes through the blade of the hopper, the blade cuts an opening at the bottom of the material bag, so as to make the material in the material bag fall into the hopper, and the mesh plate arranged on the surface of the hopper can block the material bag from falling into the hopper, thereby realizing the separation of the material and the material bag. However, the existing mesh plate and blade have significant defects in actual application, and the structure design leads to large dismounting difficulty. When the mesh plate and the blade need to be cleaned, maintained or replaced, the cumbersome dismounting process not only consumes a lot of time and labor cost, but also reduces the operation efficiency of the equipment.
